摘要

NexTech Materials is collaborating with Siemens Westinghouse on the development of a low-cost electrolyte deposition process to replace electrochemical vapor deposition for the Siemens Westinghouse tubular SOFC. The approach being pursued involves preparation of a dispersed suspension of nanoscale yttrium-stabilized zirconia (YSZ) crystallites, deposition of green YSZ electrolyte films onto lanthanum manganite (LSM) cathode tubes, and sintering of the deposited YSZ films to full density. A hydrothermal synthesis process is being used to prepare the nanoscale YSZ suspensions, and process enhancements have been made to achieve nearly complete dispersion of the YSZ crystallites in aqueous suspensions. Simple dip coating and spray coating methods are being used to deposit YSZ electrolyte films from the dispersed suspensions onto LSM tube sections. With suitable modifications to the suspension chemistry and deposition methods, sintered YSZ films have been prepared that are continuous and crack-free. Efforts also are underway to scale up the YSZ synthesis process using a novel continuous reactor system. NexTech's recent progress on this program is described in this paper.
